Hello Yofie Setiawan,
Thank you for bringing this to our attention. I'm sorry for the inconvenience you're experiencing with the media folder.
To help me investigate this issue thoroughly, would you be willing to grant me temporary administrative access to your site? This will allow me to diagnose and resolve the problem more effectively.
Before providing credentials, I highly recommend creating a full backup of your site to ensure the security of your data.
Looking forward to your response.
Best regards
